Sully is named after former airline pilot Chesley B. “Sully” Sullenberger III, who became famous for landing a damaged passenger jet on the Hudson River and saving all 155 passengers and crew in 2009.

A highly trained service dog, Sully will now go back into service to help other veterans and is going to Walter Reed National Military Medical Center, former President George W. Bush wrote in an Instagram post.

“As much as our family is going to miss this dog, we’re comforted to know he’ll bring the same joy to his new home, Walter Reed, that he brought to 41,” Bush wrote.

Sully can perform a two-page list of commands, including answering the phone and fetching items.

“As one person said, he can do just about anything except make you a martini, but not to worry, he can go get you someone to make you a martini,” McGrath said in June.

He was trained by America’s VetDogs and developed his own huge following on Instagram, @sullyhwbush. America’s VetDogs is a charity that provides service dogs to veterans, active-duty service members and first responders with disabilities.

A great joy to welcome home the newest member of our family, "Sully," a beautiful — and beautifully trained — lab from @AmericasVetDogs. Could not be more grateful, especially for their commitment to our veterans. pic.twitter.com/Fx4ZCZAJT8
